It was, yeah. A lot of the infrastructure was still standing from when it was Oculus so it felt super detached from everything else.

As for the 80B, I can confidently say that a solid chunk of that went to software licenses, believe it or not. They were spending millions a year on their on-prem GitHub Enterprise server alone, which was technically redundant because the rest of Meta had an in-house Mercurial megarepo that, surprisingly, worked really well. They may have moved off of that by now, though, since I was last employed there in 2024.
